MUSIC HALL OF CINCINNATI Everyone agrees that America’s concert halls, many built during eras of explosive interest in classical music, are now too large to fill consistently. But is there the money and the will to fix them? Cincinnati has found a way: The imposing Music Hall (from 1878), home to the meatily authentic Cincinnati Symphony Orchestra, closed for a year and reduced its capacity to around 2,400 from 3,400. It reopens, those seats (it is hoped) full, with works by Scriabin, Beethoven, John Adams and Jonathan Bailey Holland. Oct. 6-7; cincinnatisymphony.org.
